Thursday’s CSExtra offers the latest reporting and commentary on space related activities from across the globe. In Washington, House appropriators express cost concerns over the future of NASA’s commercial crew development initiative as they prepare to mark up the agency’s 2013 spending measure. New studies suggest the Earth was a more frequent target of meteor strikes in an early era than previously believed. Fragments found in northern California likely came from a minivan sized meteor that exploded over the region early Sunday. Climate change will be a campaign issue, U. S. President Obama predicts. The commercial venture Planetary Resources created a stir this week as its noted investors unveiled plans to prospect near Earth asteroids — but don’t expect too much, too soon, caution experts. More from U. S. astrophysicist Neil deGrasse Tyson on the value of science to the nation’s future economic strength. In some U. S. cities, complaints are rising over the proliferation of satellite TV dishes. India launches an Earth observing satellite.
1. From Spacepolitics.com: House appropriators urge caution as NASA moves ahead with efforts to nurture a commercial crew transportation capability for the launching of NASA astronauts to low Earth orbit. After assessing an overall price tag of $4.86 billion, lawmakers suggest that NASA consider the funding outlook for non defense discretionary agencies, then look closely at backing one company with most of the money available, plus a second company as the agency can. NASA is currently funding efforts by four companies.
